IMPROVEMENT IN HANGERS FOR SHAFTING.

Specification forming part of Letters Patent No. 185.840, dated January2, 1877 application filed July 3,1876.

To all whom it may concern:

Be it known that I, JOSEPH M. STONE, of North Andover, in the county ofEssex and State of Massachusetts, have invented an Improved Hanger forShat'ting, of which the following is a specification:

My invention relates to an improved mode of constructing the details ofa hanger, by which both the efficiency and economy of construction areincreased; and consists, in the filst place, in the new method ofconstructing the body of the hanger with a removable piece, which isfitted to the body by casting the same upon and around the said piece.the contact surfaces of which are of such form that the saidfilling-piece may be freely re moved, and also be firmly held in thebody, to

aid it in preserving its strength and form; and it also consists in theuse, in combination with the body of the hanger, of a staybolt, whichtraverses the filling piece, which unites the upper and lower jaws ofthe hanger firmly together, and also supports the drippan; and it alsoconsists in an improved drippan, and manner of supporting the same,whichwill be described; and it also consists in a new method ofconstructing the ball-joint which holds the box in the body of thehanger, and provides for its adjustment in line.

In the drawing, Figure l is a side elevation of the hanger complete.Fig. 2 is a transverse sectional elevation on the line of the shaft.Fig. 3 is a transverse sectional elevation on the line a I), through thecenter of the stay-bolt and the filling-piece and body of the hanger.

A is the body of the hanger, which is made with two cylindrical sockets,B B, above and below the shaft, in the same vertical line, in which arefitted two cylindrical blocks, 0 O, the inner ends of which are madeconcave, to fit the spherical surfaces D D of the central hearing, whichsupports the box E E. The shaft is adjusted as to its vertical height bythe screws F F, which bear against the outer ends of the blocks 0 G,which are, in turn, held'fixed by the setscrews G G. By thisconstruction the box E E is capable of being rocked to a limited extentin every direction.

A is a filling-piece, so called, which is made upon the outsidesymmetrical with the rest of the hanger, and is fitted to its place inthe hanger by the casting of the hanger itself. It is so formed, whereit fits the other part of the hanger, as to leave a space through whichthe shaft and its box can be removed, and its ends are so beveled orinclined as to afford a lateral support for the same in the body of thehanger. Through this piece, and continued in the leg of the hanger, ahole is cored, as is shown in Fig. 3, which receives the stay-bolt H,which is fastened at its upper end by being screwed into the nut I,which is also cast into the hanger, and is held in position in the moldby the core which forms the hole for the stay-bolt H.

In molding this hanger, after the pattern is withdrawn, thefilling-piece Ajust fills the mold at its proper place, and forms theprincipal support to the core which forms the hole for the stay-bolt,and holds the nut I in the proper position in the mold.

After the hanger has been cast, the fillingpiece can be driven out ofits place by a light blow of the hammer, and replaced in the samemanner; and when the stay-bolt H is screwed in place the nut J isscrewed up firmly, which makes this side of the hanger as strong as theother side.

K is the drip-pan, which is made with a central recess to receive thelower set screw F. It is provided with an inner rim, K, which preventsthe drip from coming in contact with the parts inclosed by it. The panis supported in place by the ear L, cast upon the same, which embracesthe lower end of the stay-bolt H, and is secured thereto by the nut J,so that the drip-pan can be at any time removed without disarranging theshaftmg.

What 1 claim is l. The combination, with the body of the hanger, of thefilling-piece A and stay-bolt H, cooperating substantially as described.

2. The drip-pan having a supportingear, L, in combination with thestay-bolt H, substantially as described.
